• Configure a NAT64 prefix to translate source IPv4 addresses of packets initiated by the IPv4

network to IPv6 addresses.

Figure 162 Network diagram

Configuration procedure

# Specify IP addresses for the interfaces on the router. The IPv6 addresses for IPv6 hosts are

calculated by the IVI prefix 2013::/32 and IPv4 addresses in the range of 20.1.1.0/24. (Details not

shown.)

# Configure IPv4 ACL 2000 to permits all IPv4 packets to pass through.

<Router> system-view

[Router] acl basic 2000

[Router-acl-basic-2000] rule permit

[Router-acl-basic-2000] quit

# Configure the router to use NAT64 prefix 2012:: 96 to translate source addresses of IPv4 packets.

The router also uses the prefix to translate destination addresses of IPv6 packets.

[Router] aft prefix-nat64 2012:: 96

# Configure the router to use IVI prefix 2013:: to translate source addresses of IPv6 packets.

[Router] aft prefix-ivi 2013::

# Configure the router to use IVI prefix 2013:: to translate destination addresses of packets permitted

by IPv4 ACL 2000.

[Router] aft v4tov6 destination acl number 2000 prefix-ivi 2013::

# Enable AFT on GigabitEthernet 2/0/1, which is connected to the IPv4 network.

[Router] interface gigabitethernet 2/0/1

[Router-GigabitEthernet2/0/1] aft enable

[Router-GigabitEthernet2/0/1] quit

# Enable AFT on GigabitEthernet 2/0/2, which is connected to the IPv6 network.

[Router] interface gigabitethernet 2/0/2

[Router-GigabitEthernet2/0/2] aft enable

[Router-GigabitEthernet2/0/2] quit

Verifying the configuration

# Verify the connectivity between IPv6 hosts and IPv4 hosts. This example pings IPv4 host A from

IPv6 host A.

D:\>ping 2012::a01:0101

Pinging 2012::a01:0101 with 32 bytes of data:

Reply from 2012::a01:0101: time=3ms

# Display information about IPv6 AFT sessions on the router.
